Question

in the triangle below b= . if nevessary round your answer to two decimal places. PICTURE IN COMMENTS pleaseplease help

Answer 1

First find angle B. What is angle B?

(Note: Three angles of a triangle add to 180 degrees).

Answer 2

96.5?

Answer 3

Correct.
Then use the Law of Sines: a / sin(A) = b / sin(B)
a = 31, A = 42 degrees, B = 96.5 degrees (you found above).
Plug the values into the above equation and solve for b.

Answer 4

for A i got -33.82... idk what im doing

Answer 5

a = 37, A = 42, B = 96.5
a / sin(A) = b / Sin(B)
37 / sin(42) = b / sin(96.5)
b = sin(96.5) * 37 / sin(42).

Set your calculator to degree mode and plug in the numbers.

Answer 6
